Thisinvention relates to lighting fixtures. Devices of thissort are usually an important factor in dressing up the room and their different arrangements in commercial;

i or'supporting the electric lampor a plurality of electric lamps on such devices and "the manner of concealing the conductors leading to'the lamp or'larnps so that-theorrramental or decorative aspect oi the fixture 2 will'not be impaired have also been iifnporj tant items to be considered. If'the orna mentation is formed separately, additionalstepsare required and attachment tothe fixture is involved. iF-ormation o'f the orna' "ornamentation and the mannerofsuppoib 'ing the lamp mounting or additional Lorna mentation,a11oth-er feature is to improve the" nientation'as an integral part of the fixture has been diifi-c'ult especially on thethin walled lamp supporting-arms where such arms are employed;

The primary obj-ct of invention i-s'to" .30 overcome the torego'ingdifficulties and Pro vide a fixture which will meet the above r'e quirernents. I p 1 To these ends I find that by formingthe lamp supporting arms of the fixture of thing 3 walled tubular stock, preferably but not necessarilyysquare cross section I am able to produce an exceedingly plea-sing aesthetic effect simply by shaping the arm lengthwise as desired, slotting-it terminally and spread 40 ing or rolling the sides of thearm falongthe' a slot back to form an ornamentation. Where the lamp or lamps are supported on thearm' y; the rolling back of the sides along the slot adapts the arm for the reception of a'lamp nipple or support which can besimply and efiectively brazed or otherwise secured in the open end of the tube between the rolled back "sides, said rolled back sides masking and,

I In addition to improving the manner-of appearance of the entire fixture and to 1sim phty-and-decrease the cost of the "entire structure.

Referring to the drawings the fixture shown in Figs. 1 to 12 inclusive comprises a support 5 in the form of a cast or otherwise formed wall bracket of brass, copper or other suitable or preferred material ornamented circumferentially at.6 and provided with a flat mounting wall 7. The base or bracket of a fixture of this type is attached to the wall or'other vertical support as by means of suit able screws and masks the outlet through which the conductors 8 (Fig. 3) extend from l/Vhile base or bracket 5 is shown of circular formation, it may be of any 'desired configuration and itmay be ornamented or trimmed as desired. The particular base shown has formed integral therewith, al- 1 though it may be brazed or otherwise secured thereto, an upwardly projecting scrolled ornament 10 and a downwardly eX- tending ornament '12.

Detachably secured to the outer surface of the mounting wall 7 of base or bracket 6, so that they may be used interchangeably with -cl iffere11t bases and different bases may be "used interchangeably with them, are a pair of arms 14 and 15. These arms 14 and 15 Teach comprises a thin walled tube of noncircular preferably square cross section. These tubulararmsmay be of copper, brass or other suitablematerial.v The upper end ofv each arm 14 and 15 is turned out at 16 and slotted longitudinally from the end at 17. Longitudinal slots 17 extend parallel to one pair of parallel opposite sides 18 of the tube and divide the other pair of sides .19 (Fig. 6) thereby dividing or bisecting the upper end of each. tubular arm into two opposed generally channel shaped ends 20 each having a flat base side terminating at its opposite ends in inturned flanges at substantially right angles thereto. The ends 20 are then spread and rolled out in opposite directions,- as by 'means ofa die or other suitable tool and in rolling said ends'20 the inturned flanges thereof are flattened gradually as shown in Figs. 7, 8, 9 and 10 into substantially theplane of the base side at their free ends. An ornamental scroll is thereby formed at the upper end of each arm 14' and 15. These ornamentations are of pleasing appearance and because of being integral with the arm, the ornamentation is exceedingly strong and sturdy. Attachment of separate ornamentation to the arm is thus avoided and formation of the ornamentation integral with the arm is facilitated. There is no attachment to become loosened and the cost of the material structure and forming or manufacture of the fixture is decreased.

I find that tubular stock of substantially square formation such as that shown lends itself admirably to this construction. The met-a1 in the flat base side 21 of each end (Figs. 1 and 11) is displaced uniformly with the result that there is no buckling or drawing of the metal in rolling or spreading. The inturned side flanges 23 are simply turned out gradually into the plane of the base side toward the ends of the arm without in the form of a crystal drop 25 maybe hung 1 by a hook and eye 26 from each lower rolled out end 20, said rolled out end in such instances forming in addition to an ornamentation, a mounting for the additional ornament.

The lower end of each arm 14 and 15 is turned out and upat 28 and each upturned end is slotted longitudinally from the end at 29. The two channel shaped sides 30 at this end of the tube are then spread or rolled back and their inturned flanges 31 flattened gradually into the plane of the base side 32 as described in connection with the opposite ends to form an ornamentation and in addition to receiveth-e lamp mounting designated generally at 35. v

Each lamp mounting is in the presentinstance similar so that a description of one will suffice for both. It comprises a nipple 36 having its lower end reduced at 37 for insertion into the open end of the tubular arm and said end is inserted and brazed,

soldered or otherwise rigidly secured in the end of the tube. -Nipple 36 projects vertically upwardly from the end of the tube between spread or. rolledback sides 20 and has flared sides 38 terminating in an annular. shoulder 39. The rolled back base sides of ends 20 hug the flared sides 38 of the *neamees upper edge and outer surface at d4; has an annular base flange45' mounted-over threaded extension 4'6 and clampedbetween shoulders and't'he lower end Ora second nipple 47 threaded upon extension 46,

3 'Cup l'?) has an 7 g p l and nipple 457 is threaded at '60 to receive a standard Edison or any other suitable or preferred lamp soclret or connector for V mounting one or more electric lamps. Nip

y ples 36 and 17 are provided fwrth aligned openings 51 an l152 through which-the 'con-. 1110110188 whichfen'ter tubes '14 "and through openings 55 (Fig. 8) and are led through the interior "of the tubes, are per-- .m-itted to extend ltor connection to the lamp socket or connector.- The cooperation between the lower end of cup a3, and nipple such as to complete the finished appearance .aboverthe spread or rolled back j ends of the tube and'the cup conceals the j connection .to thelamp socket from view below.

[Plate or disc 62 has a central opening 68 for registration with -a threaded opening in block 58 and with a registering opening in the mounting Wall of plate or base 5 and'a threaded stem 64 having an ornamented head or button 65 brazed or otherwise secured thereon for 00- operation" with 7 plate 62 extends loosely 7 block 58 and base 5 to hold plate or disk the conductors is thereby effectivelycon 62 securely in place.

In the modification shown in Flgs. 13 and 14, the tubular arm is againof square cross section with one end slotted at 72 and rolled back and gradually flattened at 73 to receive the lamp mounting 74 and to form an ornamentation adjacent the lamp mounting, the rolled-back ends again cooperating be employed within securely in place; The, opposite end of the tube is slotted longitddinally 'fl'zvom its at 76 and-th-eside portions 7 8 are rolled *andgradually tlattegned to form an orna- 'inentat-lon and to receive an additional orinternal annular flange 48 nament 8'0, Grnament"8O is shownin the term or a relatively long fcurvedlcaifed ten-,.

I do not wish to limit the invention to such no stock of substantially squarecross section is deslrable, stock of round elliptical or of tubing but'wishto point out that it is easier 1 to handle tubing which has its opposite sides parallel and also parallel'to the plane of the initial slotting Tubing having a cross section of any arrangement of flat 'sideswill fulfill the requirement. A-cross section of a regular polygon of an even number vof sides such as a square, hexagon, octagon is suitable. 4

I do not wish to limit the invention to opposite scrolls because the effect maybe obtalned by one, two or'more scrolls. As

I ably fitted because the slotting of opposite above pointed out, the employment of a flat side as the basis of the scroll, and the merging ot adjacent walls into such scrolls may ,be secured in a varletyrot ways. For example in a tube employing a hexagonal cross section may be slotted along three nonad acent sides and thus three scrolls formed.

It is obvious that a square tube is admirsides is easily accomplished at one operation. A complete scroll or spiral of 360 degrees is not contemplated as necessary to the mven- 'tion. Any suitable part of the same is sufiicient.

' I also wish to call attention to the fact that the itting of the tube frees the walls so that as the freed portion is bent into a .scroll or spiral the curvature of the cross ends turned back into scrolls, those at one end at least being substantially symmetrical and formed to support a lamp mounting therebetween. 7

2. A lighting fixture comprising; a supportand at least one hollow arm attached intermediate its ends to the support, said arm having a polygonalcross section preferably in the form of a square and split at .bothends substantially on a line joining the middle oftwo opposite sides and these split ends turned back into scrolls which vary gradually in cross sectlon, those at one end at least, being formed to receive a lamp mounting. i .3. A lighting fixture comprising; a support and at least one hollow arm attached to said support, said arm being constructed of material which can be rea ily split and rolled and the arm at one end'at least, being split and rolled back into scrolls so as .to support a lamp mounting between the scrolls. 4. In a lighting fixture, a support, a tubular arm slotted terminally and having its sides adjacent the slots spread outwardly and flattened gradually, the said sides of the slots being adapted to receive a lamp mounting, a conductor entering the arm adjacent its attachment to the support, and means concealing the attachment of the arm to the support and the entry of the conductor into the arm. 1 v

5. In a lighting fixture, a Wall bracket, a plurality of lamp supporting arms slotted terminally and having their sides formed into scrolls Which vary gradually in cross section from a section of a portion of the tube to a section of a flat sheet, said scrolls beingadapted to receive lamp. mountings, the arms and bracket havingv apertures for the introduction of conductors into the arms for extension therethrough, a mounting member attached to and rigidly joining the arms, means cooperable with the bracket and said mounting member for attaching the arms-to the bracket, a plateconcealingsaid attachment and the introduction of the conductors into the arms, and means cooperable with the mounting member in said plate for mounting the plate in place. ,7
